Of these, the control unit
When your vehicle is on standby to enter the priority road
The number of passing vehicles approaching and distant from the own vehicle on the priority road after the start of the approach waiting state and / or the elapsed time after the start of the approach waiting state are counted to acquire standby data. , A sign is displayed on the display unit based on the standby data.
The own vehicle means a vehicle equipped with the traveling state transmission system for a vehicle of the present invention.

In short, the vehicle traveling state transmission system of the present invention includes a display unit for displaying a sign toward the outside of the vehicle and a control unit for displaying the sign on the display unit. It can also be called a kind of so-called digital signage.

In the vehicle traveling state transmission system of the present invention, when the own vehicle is in the approach standby state, that is, in the state of trying to enter the priority road, the control unit displays a sign on the display unit based on the standby data. In other words, the vehicle traveling state transmission system of the present invention, when the own vehicle is in the approach standby state, is waiting for the vehicle passing through the priority road to enter the priority road, and the number of passing vehicles. The degree of waiting such as is displayed. This can have a psychological effect on the driver of the vehicle traveling on the priority road.
Psychologically affecting the driver of a vehicle traveling on a priority road reminds the driver to give way for his vehicle, which in turn reduces the waiting time for his vehicle to enter. Can contribute.

In addition, the priority road in this specification means that the vehicle traveling on the road is another road (that is, a non-priority road) because there is no obligation to slow down when entering an intersection where traffic control is not performed. It means a road that is allowed to travel preferentially to vehicles merging on the road.
The priority roads and non-priority roads referred to here include parking lots such as service areas. For example, in the relationship between the road (a) and the parking lot (b) connecting to the road (a), the road (a) may be called a priority road and the parking lot (b) may be called a non-priority road. Further, the above-mentioned priority road can be read as a certain lane (a) of one road, and the non-priority road can be read as another lane (b) of the same road. For example, there is a case where the lane (b) joins the lane (a) due to a decrease in the width or construction of the lane (b).

In the vehicle traveling state transmission system of the present invention, the sign displayed on the display unit is the number of passing vehicles approaching and distant from the own vehicle on the priority road after the start of the approach standby state, and / or the approach standby of the own vehicle. It is based on the wait data that counts the time. Thereby, the traveling state transmission system for a vehicle of the present invention can inform the driver of the vehicle traveling on the priority road of the degree of standby of the own vehicle. If the degree of waiting is excessive, it is expected that the psychological effect on the driver of the vehicle traveling on the priority road will also be large, and it is expected that the approach waiting time of the own vehicle will be shortened. Will be done.

Hereinafter, the vehicle traveling state transmission system of the present invention will be described for each component thereof.

The display unit may be any as long as it can face the outside of the vehicle and display a sign, and the display mechanism thereof is not particularly limited. For example, as a display unit, a display that displays an image or video by various display elements such as an LED light, an organic EL element, or a liquid crystal display, a screen that transmits or reflects an image or video projected by a projector, and the like can be exemplified. It is possible.
The display unit may be arranged outside the vehicle or inside the vehicle as long as the display unit can display the sign toward the outside of the vehicle and the outside of the vehicle.

The display unit may be arranged at various positions in the vehicle. The places where the display unit can be preferably arranged in the vehicle are the front window FW, the rear window RW, the bonnet B, the side door SD, the back door BD, the front bumper FB, the rear bumper RB, the front fender FF, and the rear as shown in FIGS. Examples include fender RF, tire wheel TW, and the like.

The traveling state transmission system for a vehicle of the present invention may be provided with only one display unit or may be provided with a plurality of display units. When the traveling state transmission system for a vehicle of the present invention includes a plurality of display units, the display units can be directed in a plurality of directions, and it is possible to inform more drivers of the degree of standby of the own vehicle. be.

Here, the vehicle traveling on the priority road on which the own vehicle is about to enter is roughly classified into two types: a vehicle approaching the own vehicle from the left side and a vehicle approaching the own vehicle from the right side. Hereinafter, if necessary, a vehicle approaching from the left side with respect to the own vehicle will be referred to as a left-handed traveling vehicle, and among these, a passing vehicle with respect to the own vehicle will be referred to as a left-handed passing vehicle. Further, hereinafter, if necessary, a vehicle approaching the own vehicle from the right side is referred to as a right-handed traveling vehicle, and among these, a passing vehicle with respect to the own vehicle is referred to as a right-handed passing vehicle.

In the vehicle traveling state transmission system of the present invention, in order to inform more drivers of the degree of standby of the own vehicle by the display unit, the left side display unit for the left side traveling vehicle facing the left side outside and the right side outside It is preferable to have both a right side display unit for a vehicle traveling on the right side and a right side display unit.
It should be noted that the right side display unit and the left side display unit may display different signs or the same sign may be displayed.

The sign displayed by the display unit may be any sign that can inform the driver of the vehicle traveling on the priority road of the degree of waiting of the own vehicle, and the degree of waiting may be directly displayed. , May be displayed indirectly.
For example, the number of passing vehicles after the start of the approach waiting state, numbers and sentences representing the approach waiting time directly or indirectly, figures such as arrows, and the like can be mentioned. Furthermore, the degree of waiting can be expressed by changing the color of the sign, for example, from blue to yellow to red.

In addition to the above-mentioned display unit, the vehicle traveling state transmission system of the present invention includes a control unit electrically connected to the display unit. The electrical connection between the control unit and the display unit may be wired or wireless as long as the display unit can be operated and controlled by the control unit. That is, the control unit may be arranged on the vehicle together with the display unit, or the control signal may be transmitted to the display unit arranged outside the vehicle and arranged on the vehicle.

When the own vehicle is in the approach standby state, the control unit acquires standby data and displays a sign based on the standby data on the display unit.

The control unit may automatically detect that the own vehicle is in the approach standby state. For example, when the destination is preset in the car navigation system, the car navigation can detect that the own vehicle is at the confluence to the priority road. In this case, the car navigation system functions as if it were a sensor for the control unit, and the control unit that receives the signal from the car navigation system can also automatically detect that the own vehicle is in the approach standby state. .. In this case, the display control to the display unit by the control unit may be automatically started by the control unit detecting that the own vehicle is in the approach standby state as a trigger.

Alternatively, it is also possible to link the turn signal and the control unit and determine that the own vehicle is in the approach standby state when the turn signal is turned on for a predetermined time. In this case, it may be said that the turn signal functions as if it were a sensor, and the control unit automatically detects that the own vehicle is in the approach standby state. Also in this case, the display control on the display unit by the control unit may be automatically started by the control unit detecting that the own vehicle is in the approach standby state as a trigger.

The display control on the display unit by the control unit may be started when the own vehicle is in the approach standby state, or may be started when the degree of standby becomes a predetermined magnitude or more. .. As the degree of standby, the elapsed time since the own vehicle is in the approach standby state and / or the number of passing vehicles can be exemplified. For example, the display control on the display unit by the control unit is started 10 seconds after the own vehicle is in the approach standby state and / or the number of passing vehicles is 5 after the own vehicle is in the approach standby state. It starts when it becomes, etc.

Alternatively, a passenger such as a driver may manually input to the control unit that the vehicle is in an approach standby state. For example, a switch for turning on / off the display control of the display unit by the control unit may be provided in the vicinity of the driver's seat. In this case, the display control on the display unit by the control unit may be started by using the on operation of the switch by the driver as a trigger.

In the vehicle traveling state transmission system of the present invention, as standby data acquired by the control unit, the number of passing vehicles approaching and distant from the own vehicle on the priority road after the start of the approach standby state of the own vehicle, and / or own The vehicle approach waiting time is adopted.

Of these, as the number of passing vehicles, only one of the described left-hand passing vehicle and right-hand passing vehicle may be counted, or both may be added up.

The traveling vehicle that should inform the degree of waiting of the own vehicle is whether the priority road is left-handed or right-handed, one-way or two-way, one-way one lane or one-sided two or more lanes. It depends on whether it is there or not. However, in order for the own vehicle waiting to enter to enter the priority road, it is necessary to at least give way to the traveling vehicle traveling in the nearest lane from the own vehicle.
Therefore, the control unit counts at least the number of passing vehicles in the lane near the own vehicle, and displays a sign corresponding to the number to the traveling vehicle traveling in the lane closer to the own vehicle by the display unit. It is preferable to display it.

For example, if the priority road is on the left side and is on the opposite side of one lane, the control unit displays a sign on the right side display unit based on the standby data obtained by counting the number of vehicles passing on the right side. preferable. It is more preferable that the sign is displayed on both the right side display part and the left side display part.
Further, in this case, it is also preferable that the control unit displays a sign on the right side display unit based on the standby data acquired by counting the sum of the number of vehicles passing on the right side and the number of vehicles passing on the left side. It is more preferable that the sign is displayed on both the right side display part and the left side display part.

In addition to the display by the display unit, it is also possible to display by other display methods. Examples of the other display method include a method of irradiating a road surface with a light to display predetermined characters, figures, and the like.

It is also preferable that the vehicle traveling state transmission system of the present invention displays a sign other than the sign based on the standby data.

For example, it is preferable that the traveling state transmission system for a vehicle of the present invention displays a thank-you sign for a traveling vehicle that has given way to its own vehicle. The sign may be displayed on a display unit that displays a sign based on standby data, or may be displayed on another display unit. The sign is preferably displayed when or after the own vehicle is entering or after entering the priority road, and the display unit for displaying the sign is displayed when or after the own vehicle is entering or after entering the priority road. It is preferable that the vehicle is in a position where it can be easily seen by a traveling vehicle that has given way to its own vehicle. Specifically, it is preferable that the display unit for displaying the thank-you sign faces the side or the rear of the vehicle.
The thank-you sign can be displayed by various methods such as sentences, figures, images and videos, as in the case of the sign based on the standby data.

Hereinafter, the traveling state transmission system for a vehicle of the present invention will be described with reference to specific examples.

(Example 1)
The vehicle traveling state transmission system of the first embodiment is mounted on a vehicle that is supposed to travel on a road traveling on the left side.
FIG. 4 shows an explanatory diagram schematically showing the operation of the vehicle running state transmission system of the first embodiment and the vehicle equipped with the vehicle running state transmission system. 5 to 7 are explanatory views schematically showing the vehicle running state transmission system of the first embodiment and the vehicle equipped with the vehicle running state transmission system.
Hereinafter, in the examples, the terms "upper, lower, left, right, front, and rear" mean the upper, lower, left, right, front, and rear shown in each figure. These directions are directions with respect to the own vehicle, and the front and the rear thereof may be referred to as the front side and the rear side of the vehicle traveling direction, respectively.

As shown in FIG. 5, the vehicle traveling state transmission system 1 of the first embodiment includes a display unit 10 and a control unit 20. Of these, the control unit 20 is arranged in the vehicle 90 and is electrically connected to the display unit 10 and also electrically connected to the ECU of the illustration and the car navigation system of the illustration mounted on the vehicle 90. ..
The control unit 20 in the vehicle traveling state transmission system 1 of the first embodiment acquires standby data from the car navigation system.

As shown in FIGS. 5 to 7, the display unit 10 in the vehicle traveling state transmission system 1 of the first embodiment is arranged outside the vehicle and faces the outside of the vehicle 90. The display unit 10 in the vehicle traveling state transmission system 1 of the first embodiment is provided on the bonnet B, the front bumper FB, the side door SD, the tire wheel TW, the back door BD, and the rear bumper RB, respectively. Each display unit 10 is individually controlled by the control unit 20.

Hereinafter, the operation of the vehicle traveling state transmission system 1 of the first embodiment will be described. In the first embodiment, as shown in FIG. 4, a case where the own vehicle 91 tries to turn left toward the priority road R2 having two lanes on each side will be described.

First, when the car navigation system predicts that the own vehicle 91 will enter the priority road R2, control is performed when the own vehicle 91 reaches the confluence of the non-priority road R1 and the priority road R2 as shown in FIG. The unit 20 determines that the own vehicle 91 is in the approach standby state based on the GPS information acquired via the car navigation system.
At this time, the control unit 20 starts counting the approach waiting time of the own vehicle and the number of passing vehicles 95 after the start of the approach waiting state.

More specifically, the control unit 20 in the vehicle traveling state transmission system 1 of the first embodiment has the own vehicle 91 within 3 meters from the end side of the above-mentioned confluence, and the own vehicle 91 stops. Alternatively, it is determined that the approach standby state has started when the turn signal for turning left of the own vehicle 91 is turned on.

The control unit 20 in the vehicle traveling state transmission system 1 of the first embodiment counts the number of passing vehicles 95 based on the GPS information acquired via the car navigation system. In the first embodiment, the priority road R2 is a road with two lanes on each side, and the own vehicle 91 is about to turn left. Therefore, here, as the number of passing vehicles 95, only the number of right-hand passing vehicles 95R in the lane L1 on the side closer to the own vehicle 91 on the priority road R2 is used among the right-hand traveling vehicles 96R approaching from the right side with respect to the own vehicle. Count and use that value as standby data.

If the own vehicle 91 starts after stopping at the above-mentioned confluence, the control unit 20 determines that the approach standby state of the own vehicle 91 has been canceled, and cancels the above-mentioned count.
In this case, if the own vehicle 91 is stopped in multiple stages, that is, if the vehicle is stopped once and then travels slightly forward, the speed is 10 km / h or less, or the distance traveled after the vehicle is stopped is 1 m. If the following, the control unit 20 determines that the approach standby state of the own vehicle 91 is continuing, and continues the counting of the passing vehicle 95.

When the approach standby state of the own vehicle 91 continues and the number of passing vehicles 95 counted reaches 5 or the approach standby time reaches 10 seconds, the control unit 20 signs the display unit 10. Is displayed.

By displaying the sign on the right side display unit 10R, it is possible to efficiently inform the driver of the right side traveling vehicle 96R, which is the target to be given the road, of the degree of standby of the own vehicle 91.

By the way, as shown in FIG. 4, since the turn signal 50L for turning left of the own vehicle 91 is on the left side of the own vehicle 91, it is difficult to see it from the right-hand traveling vehicle 96R.
However, as shown in FIGS. 5 and 6, the control unit 20 in the vehicle traveling state transmission system 1 of the first embodiment displays an arrow sign indicating a left turn on the display unit 101 on the right side of the front bumper FB. .. As a result, the vehicle traveling state transmission system 1 of the first embodiment can transmit the traveling direction of the own vehicle 91 to the driver of the right-hand traveling vehicle 96R, which is the target to be given the way.

When the right-hand vehicle 96R traveling on the priority road R2 notices the sign of the display unit 10 and gives way to the own vehicle 91, the own vehicle 91 can turn left and enter the priority road R2. At this time, the turn signal 50L for turning left is turned off, and the own vehicle 91 turns the rear part of the vehicle 90 toward the right-hand traveling vehicle 96R. The control unit 20 determines that the own vehicle 91 has entered the priority road R2 based on the GPS information acquired via the car navigation system and the turn signal off information, and determines that the vehicle 91 has entered the priority road R2, and the display unit 102 of the back door BD and the control unit 20. A thank-you sign is displayed on the display unit 103 of the rear bumper RB. Specifically, as shown in FIG. 7, it is a sign of the characters "Thank you" and "Thank you" and a sign of a smiling pictogram.
As a result, according to the vehicle traveling state transmission system 1 of the first embodiment, it is possible to convey gratitude to the driver of the right-hand traveling vehicle 96R who has given way to the own vehicle 91.
